Abstract

An improved Z-shaped sheet piling ( 15 ) comprising a first flange ( 16 ), a second flange ( 18 ), a web ( 19 ), a junction ( 20 ) between the first flange and the web, the junction having an inner surface ( 44 ), the inner surface defined by at least a first radius ( 23 a ) and a second radius ( 23 b ). The inner surface may be further defined by a third radius ( 23 c ). The sheet piling may comprise a first flange ( 16 ) having a substantially planar flange surface ( 37 ), a second flange ( 18 ), a web ( 19 ) having a substantially planar web surface ( 39 ), a junction ( 20 ) between the first flange and the web, the junction having a fillet portion ( 43 ) defined by the planes of the web surface and flange surface extended to an intersection ( 59 ) and an inner substantially arcuate surface ( 44 ) intersecting the web surface and flange surface, the inner arcuate surface defined by at least a first radius ( 23 a ) and a second radius ( 23 b ). The inner arcuate surface may be further defined by a third radius ( 23 c ).

Claims

exact text as granted — not AI-modified
1. A Z-shaped sheet piling comprising:
 a first flange; 
 a second flange; 
 a web; 
 a junction between said first flange and said web; 
 said junction having substantially concave inner surface; 
 said inner surface comprising at least a first concave surface of a first radius and a second concave surface of a second radius that is different from said first radius; 
 thereby allowing for selective strengthening of the piling with respect to transverse stresses. 
 
   
   
     2. The Z-shaped sheet piling of  claim 1 , wherein said inner surface further comprises a third concave surface of a third radius that is different from said second radius. 
   
   
     3. A Z-shaped sheet piling comprising:
 a first flange having a substantially planar flange surface; 
 a second flange; 
 a web having a substantially planar web surface; 
 a junction between said first flange and said web; 
 said junction having a fillet portion defined by said planes of said web surface and said flange surface extended to an imaginary intersection of said planes and substantially concave inner surface extending between said web surface and said flange surface; 
 said inner surface comprising at least a first concave surface of a first radius and a second concave surface of a second radius that is different from said first radius; 
 thereby allowing for selective strengthening of the piling with respect to transverse stresses. 
 
   
   
     4. The Z-shaped sheet piling of  claim 3 , wherein said inner surface further comprises a third concave surface of a third radius that is different from said second radius.
